Serial No. 116.782. CNo model.)

To all whom it may concern:-

Be it known that I, MORTEN BALTAZAR HANSEN, manufacturer, of Gothersgade65, Copenhagen, in the Kingdom of Denmark,

5 have invented certain new and useful Improvements in LubricatingApparatus; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being bad to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

The present invention refers to an apparatus adapted for lubricatingmovable machine parts with a mixture of oil and graphite or similarlubricant-s. The apparatus is constructed in such a manner that a veryexact and instantaneous regulation of the quantity of graphite inproportion to the oil can be efiected.

The invention is illustrated in the accompanying drawings, in which-Figures 1 and 2 represent two vertical longitudinal sections through theapparatus drawn at right angles toeach other, and Fig. 3 is a section onthe line A B of Fig. 2.

a is a tube, of glass, metal, or other suitable material, provided withtop and bottom covers b and c, pressed tightly against the edge of thetube by means of screw-bolts d. (See Fig. 3.) In this way aperfectly-tight chamber e, called the mixing-chamber, is formed insidethe tube a. Above the top cover b is arranged a filling-cup f,communicating with the mixing-chamber 6 through a passage g, that may beclosed and opened by means of a hand-valve h. The passage g opens into atube 11, reaching almost down to the bottom of the chamber e. In thebottom cover a is also arranged a passage k, opening into a tube m,extending upward into the mixing-chamber e and reaching almost to thetop of this chamber. The passage is may by means of a handvalve n bemade to communicate with a channel in the bottom cover a, into whichchannel is screwed a conical tube or union 1), capable of beingconnected with an oil-pump of a suitable type. Through the channel 0 ispassed a screw 1', having an angular passage .will then pour from thepipe The upper end of the screw 0" reaches up into the chamber e, sothat the channel 0, and consequently also the conduit from the oilpump,is in connection with the chamber 6 through the passage q. The screw ris termed the regulating-screw. Lastly, the bottom cover 0 is providedwith a part 5, projecting into the chamber e and having a passage t,whose one end opens out into the chamber 2 through a passage u in ascrew '22, placed so that the passages q and u are lying in line witheach other. The other end of the passage t is carried out through thebottom cover 0 and connected with a conduit leading the oil and graphitemixture to that part of the machine which it is desired to lubricate.The passage t is provided with a check-valve w.

The apparatus is, as mentioned,inserted in the pipe-conduit leading fromthe oil-pump to the spot where the lubrication is required and ismounted as near to this place as circumstances will permit.

Before the apparatus is to act the chamber e is completely filled withoil from the oil- In order to fill the chamber 6, the regulating-screw ris screwed up against the screw '2), the ends of these screws beingshaped so as to be able to form a tight joint. valves h and n are thenopened and the piston of the oil-pump pressed down. The oil or into thechamber e, the compressed air escaping through a small passage a; in thetop cover I). When the oil begins to flow out through the passage as,this latter is closed by means of a screwplug y and the filling-cup f isfilled with a mixture consisting of graphite ground in oil. The pistonof the oil-pump is then raised, whereby the graphite and oil mixturefrom the filling-cup is sucked down through the passage g and the tube1' into the chamber e, which it fills from below, while the oil fromthis chamber is sucked out through the tube 5 m, the passages 7c and 0,and back again to the oil-pump. When the mixture of graphite and oil hasfilled the chamber e to about one inch from the top cover I), the motionof the pump-piston has stopped and the hand- 10 valves h and n closed.The apparatus is now ready to work. The oil-pump being then The'haud- 8ostarted in the usual manner the oilwill be forced through the conicaltube p Baud? thence through the passages 0 andqtto the'.

passage u of the screw o, whence the-oil will pass through the passaget, fitted with the check-valve w, to the place to be lubricated,

the oil being constantly under pressure ts) the oil-pump.

As long as the regulating-screw? is screwed up against the screw l) theoil from the oil pump will pass unmixed through theappar' tus and thepart to be lubricated will receive pure oil only; but when the regulatingsscrew 1' is screwed down a little, so that therefwill'be some distancebetween the ends of the .twd

screws, the oil flowing from the passage q will rise through the spacebetween the two: screws filled with a mixture of oil and graph-'1 iteand carry along some of the graphite; j

Experience shows that the oil willfiow through the passage u and fartheron tothe machine part to be lubricated mixed with graphite in aproportion dependent only on the distance between the two screw ends andr, so that the greater this distance th larger will be the quantity ofgraphite con i tained in the oil passing through the passag u. Theamount of graphite in the mixture,

in the chamber 6, however, is withoutj ll yr H influence upon thequantity of graphite inthti lubricating-oil. a

As pure oil is constantly introduced an corresponding quantity of oiland graphitels drawn off, the amount of pure oil which fills the upperpart of the chamber 6 will gradu:

ally increase, while the quantity of graphite in the chamber e decreasesin the same "proportion. refilled occasionally in the before-describemanner. v

Experiments have shown that by mean of this apparatus the quantity ofgraphite'in the lubricating-oil can be regulatedat pleasure and withinwide limits. It has thus been possible with the same filling of thechamber 6 to lubricate with oil in which the quantit y, of graphite washardly visible, as well as with I oil whose contents of graphite were sogreat that the oil was quite thick, and, lastly, withoil containing anyquantity of graphite between these two extremes. screws 1" and 5 neednot absolutely be cal, as shown on the drawings. 7

By means of the described apparatus and by adjusting theregulating-screw r it becomes possible to obtain any desirableproportion of graphite and oil mixture, and this proportion willinstantaneously be altered when the position of the screw '1" ischanged.

As it is at the part to be lubricated that changes in the mixture shalltake efiect, the

distance between the said part and the regug lating-screw should be assmall as possible, while the distance between the apparatus and thelubricator-pu mp is of no consequence.

The chamber e must therefore be,
